We have had 2.8 bar on the road. So no not ridiculous boost at all 
Can never understand people who wont run high boost. No point in having a great big air pump bolted to your engine and not using it. Utter gayness

Well i run my t34 wide open, so as much boost as it could make everywhere in the rev range. Turbo lasted a good few k miles.
The GT30 i have done maybe 3k miles at the boost. I expect the turbo to show signs of wear before my engine does. I do now wish i had long studded my engine but never mind. It does what it does
Certainly not going to turn the boost down to preserve engine life. Boost generally doesnt cause problems, its too much igntion and lack of fuel which does. Although i am no expert so am prepared to be corrected

erm............
Keeping the cossie for now. Got a baby on the way due in June. Cant be arsed with the hassle of breaking a car and trying to shift the bits. If someone offered me the right money for the whole car so they could drive it or break themselves then i would probably let it go.
But for now i will keep it and wait for the weather to improve and enjoy it

No the 3071 is the limit. The point of my exercise was to see how far i could go with the standard head. We have far exceeded my estimations and Mark's. The next turbo up is the 3076. Mark thinks i will suffer from surge. At the moment i do not have to cap or control the boost lower in the rev range. If someone gave me a 3076 (internal gate) to try i would glady give it a try and see what the results are and then hand it back but i am not forking out £1k just to find out lol
Same box as Rod if mine lets go or i may see what Bara offer. This is budget spec after all

Dave, agree with that ^^^^^^^ 100% mate, i,ve said it until i,m sick of saying it, hated the T38 on my saff, terrible to drive, lifeless below 4k..
pointless imo..
Yes 2 types, one looks like a T34 and the other abit like a T4, i had the Universal Turbo T38 which resemble a T34 where-as the Turbo Technic looks like a T4...Phewwwww
I personally now wouldn,t choose a T38, the GT3071 is making nice power on cars, Evos aswell and the spool is similar to a T34 so i believe from Karl/Sheady etc...

Took mine out today for the first time after fitting the T38
All i can say is your spec must not of suited the turbo as mine makes positive boost by 2250rpm and is making 1bar at 3250rpm, thats only on the get me to Tony chip he sent as well.

Steve,
My spec as you call it...
i think you mean JIM,S spec WASN,T meant for a T38 mate, it was built for a T4 which Jim had bought brand new but for some reason decided on PX-ing it for a new T38......
